2024-02-07Use reverse to fundamental types semantics in $json.member_value()Boris Kolpackov1-1/+1
Feels like this is an equivalent context to subscript/iteration.
2024-02-07Map JSON null in subscript/iteration to [null] instead of emptyBoris Kolpackov1-6/+14
This in fact feels more natural in the "for consumption" model and also helps with the nested subscript semantics.
2024-02-07Add support for nested subscript, use for json accessBoris Kolpackov1-0/+29
2024-02-07Add experimental support for JSON value typesBoris Kolpackov5-0/+651
New types: json json_array json_object New functions: $json.value_type(<json>) $json.value_size(<json>) $json.member_{name,value}(<json-member>) $json.object_names(<json-object>) $json.array_size(<json-array>) $json.array_find(<json-array>, <json>) $json.array_find_index(<json-array>, <json>) $json.load(<path>) $json.parse(<text>) $json.serialize(<json>[, <indentation>]) For example, to load a JSON value from a file: j = $json.load($src_base/board.json) Or to construct it in a buildfile: j = [json] one@1 two@([json] 2 3 4) three@([json] x@1 y@-1) This can also be done incrementally with append/prepend: j = [json_object] j += one@1 j += two@([json] 2 3 4) j += three@([json] x@1 y@-1) Instead of using this JSON-like syntax, one can also specify valid JSON input text: j = [json] '{"one":1, "two":[2, 3, 4], "three":{"x":1, "y":-1}' Besides the above set of functions, other handy ways to access components in a JSON value are iteration and subscript. For example: for m: $j print $member_name($m) $member_value($m) print ($j[three]) A subscript can be nested: print ($j[two][1]) print ($j[three][x]) While a JSON value can be printed directly like any other value, the representation will not be pretty-printed. As a result, for complex JSON values, printing a serialized representation might be a more readable option: info $serialize($j)

2023-06-07Re-disable C++20 modules tests for MinGW GCCBoris Kolpackov1-3/+1
Several tests (other than the expected symexport) are still failing due to what looks like Windows-specific bugs in the compiler.

2022-12-15Improve escape sequence supportBoris Kolpackov1-0/+17
Specifically: 1. In the double-quoted strings we now only do effective escaping of the special `$("\` characters plus `)` for symmetry. 2. There is now support for "escape sequence expansion" in the form $\X where \X can be any of the C/C++ simple escape sequences (\n, \t, etc) plus \0 (which in C/C++ is an octal escape sequence). For example: info "foo$\n$\tbar$\n$\tbaz" Will print: buildfile:1:1: info: foo bar baz
2022-12-14Improve empty simple value to empty list of names reduction heuristicsBoris Kolpackov1-0/+55
Specifically, do not reduce typed RHS empty simple values for prepend/append and additionally for assignment provided LHS is typed and is a container.
2022-12-14Handle NULL values in $string() and $concat() functionsBoris Kolpackov1-0/+42
This is relied upon by the parser to provide conversion/concatenation semantics consistent with untyped values. Note that we handle NULL values only for types that have empty representation.
2022-12-02Fail if scope or target qualification in variable expansion is unknownBoris Kolpackov2-0/+21
There are three options here: we can "fall through" to an outer scope (there is always the global scope backstop; this is the old semantics, sort of), we can return NULL straight away, or we can fail. It feels like in most cases unknown scope or target is a mistake and doing anything other than failing is just making things harder to debug.

2022-09-29Add $find(<sequence>, <value>), $find_index(<sequence>, <value>) functionsBoris Kolpackov4-2/+60
The $find() function returns true if the sequence contains the specified value. The $find_index() function returns the index of the first element in the sequence that is equal to the specified value or $size(<sequence>) if none is found. For string sequences, it's possible to request case- insensitive comparison with a flag.

2022-09-23Add $is_a(<name>, <target-type>), $filter[_out](<names>, <target-types>) ↵Boris Kolpackov1-0/+36
functions $is_a() returns true if the <name>'s target type is-a <target-type>. Note that this is a dynamic type check that takes into account target type inheritance. $filter[_out]() return names with target types which are-a (filter) or not are-a (filter_out) one of <target-types>. In particular, these functions are useful for filtering prerequisite targets ($<) in ad hoc recipes and rules.
2022-09-22Add $integer_sequence(<begin>, <end>[, <step>]) functionBoris Kolpackov1-0/+8
It returns the list of uint64 integers starting from <begin> (including) to <end> (excluding) with the specified <step> or 1 if unspecified. For example: hdr = foo.hxx bar.hxx baz.hxx src = foo.cxx bar.cxx baz.cxx assert ($size($hdr) == $size($src)) "hdr and src expected to be parallel" for i: $integer_sequence(0, $size($hdr)) { h = ($hdr[$i]) s = ($src[$i]) ... }
2022-09-22Add support for hex notation for uint64 typeBoris Kolpackov1-0/+8
Specifically, now we can do: x = [uint64] 0x0000ffff cxx.poptions += "-DOFFSET=$x" # -DOFFSET=65535 cxx.poptions += "-DOFFSET=$string($x, 16)" # -DOFFSET=0xffff cxx.poptions += "-DOFFSET=$string($x, 16, 8)" # -DOFFSET=0x0000ffff Note that there is no hex notation support for the int64 (signed) type.
